Proxxon Tungsten Carbide Cut-Off Wheel — ×20mm, 2mm Thick, 2.35mm Shank, Wood, CFK, GRP & Rubber (No. 28838)

The Proxxon Tungsten Carbide Cut-Off Wheel (No. 28838) is a ×20mm tungsten carbide cutting disc for Proxxon Micromot tools, supplied with mandrel on a 2.35mm shank. At 2mm thick, this is a robust cut-off wheel for slitting, parting, and profiling in wood, carbon fiber (CFK), glass fiber reinforced plastic (GRP), rubber, and silicone — materials where standard abrasive cut-off wheels would wear rapidly or clog.

Cooling holes in the disc body reduce heat buildup during cutting — critical when cutting heat-sensitive materials like rubber and silicone, and when making extended cuts in CFK and GRP where friction heat can delaminate fibers. Tungsten carbide construction maintains cutting performance far longer than abrasive discs in these abrasive composite materials.

Key Features

• Tungsten carbide construction — long life in abrasive materials (CFK, GRP) where abrasive discs wear rapidly
• Cooling holes — reduce heat buildup; critical for rubber, silicone, and composite cutting
• ×20mm diameter — compact size for precision slitting and profiling in Micromot tools
• 2mm thickness — robust cut-off wheel for controlled parting and slitting
• Supplied with mandrel — ready to use on 2.35mm shank Micromot tools

Applications

• Slitting and parting in wood
• Carbon fiber (CFK) cutting and profiling
• GRP (glass fiber reinforced plastic) cutting
• Rubber and silicone slitting
